    We can't Activate Windows On This Device


    I have a Win 10 pro digital license for my PC (and a separate one for my laptop). I have had the same license's for a couple of years. I have reinstalled and reloaded system images too many times that I can remember.
    I share a Microsoft account with my laptop (same email address)

    Today for the first time since my fresh install of the creative update (which has been working perfectly with the same digital license as I always use) I had to do a system image restore. These messages don't make sense as they seem contradictory in the sense that it is asking me to install Win 10 pro to fix my issue, which is the OS giving me the errors.

    If I click on "I changed hardware" (for the hellofit) I only see my laptop and no longer see my PC. However they are both present when logging into my Microsoft Account. This is all new to me.

    I would hate to think that from now on, maybe because the Creative update is made of different stuff, that I have to do a fresh install of Win 10 as apposed to the convenience of a Win 10 built in made System Image.

    Any thoughts.
    I did see that this was a thing last year also with a few people but nothing has helped me so far.

    yelp!

    If it helps, your error code 0xC004F034 apparently means...

    0xC004F034 You might see this error if you entered an invalid product key or a product key for a different version of Windows.

    Enter a valid product key that matches the version and edition of Windows 10 installed on your device.

    If Windows is installed on a device that connects to a Key Management Service (KMS) server, contact your organization's support person for more info about how to activate Windows.

    Yeah, thanks Bree. I don't enter a key, never have, always digital (email) it has always been my email address and confirmation by logging into my Microsoft account.

    If "for a different version of Windows." means windows "Anniversary Update" as apposed to "Creative Update" then a new piece of chalk and a drawing board would do MS well.

    It may be that when the Troubleshooter said "We have found a Windows 10 Pro license for this device..." it was referring to a digital license tied to the machine's hardware, not to your Microsoft account. Try entering the Windows 10 Pro generic product key:

    No, one key should work for all...

    Thanks for the try Bree. generic didn't work.
    There is a long history with my account and key. Originally it was a Win 8 freebie from Robin (here) and evolved to what it is today, an email account with MS for Win10Pro. I have no idea what happened to the original Win 8 key key Robin gave me.

    If I have to and it will save me from kicking the crap out of my PC or buying Microsoft and sacking everyone, I'll just purchase a new key. I have way too much work to do to worry, too much.

    I suppose I could do a fresh install and do it the long way using my MS account, but I'd freak out and blow chunks if it happened again in the future.

    I am still lost with it asking me to install Win 10 Pro to take advantage of the digital license for a machine already running ... Win 10 pro.

    Maybe it would be happy with an in-place repair install, at least you would keep your files and apps that way.

    That's a thought, thanks Bree. I shall try it in the morning after I get this Monitor removed from my foot.

    Thank you NavyLCDR. Before I seen this message I thought I'd give re-installing the Image again and for some reason this time upon completion there was no longer an issue. I have bookmarked your cmd suggestion for future reference. I appreciate both of you taking the time to help me out.

    Cheers

    P.S. My apologies for originally posting this thread in the wrong section.
